From the newest apps to the most established platforms, mobile is in constant motion.

"Showrooming" is alternately feared and adopted, as retailers experiment with adding mobile to the shopping experience. App design is increasingly accessible. Tablet sizes are shrinking. International usage is exploding. Mobile is fragmenting. The HTML5 debate rages on.

So who’s disrupting whom, exactly? Find out at Business Insider's second-annual IGNITION West on March 26, 2013, in San Francisco.

This year’s event will bring together industry leaders to share their thoughts on why and how mobile is disrupting your business, your products, and your consumers. You’ll hear from organizations that are moving their operations onto mobile platforms, with all the challenges and changes that entails.

Also back – by popular demand – is Ben Schachter, senior analyst with Macquarie Capital, to share his thoughts on mobile market shifts. In the meantime, you can browse Business Insider’s “Future of Mobile” 2012 research presentation.
